Voyager 2 discovered previously unknown Neptunian rings, [64] and confirmed six new moons: Despina, Galatea, Larissa, Proteus, Naiad and Thalassa. [65] [C] While in the neighborhood of Neptune, Voyager 2 discovered the "Great Dark Spot", which has since disappeared, according to observations by the Hubble Space Telescope. [66]
Voyager 2 spacecraft. On 25 August, in Voyager 2 's last planetary encounter, the spacecraft swooped only 4,950 km (3,080 mi) above Neptune's north pole, the closest approach it had made to any body since it left Earth in 1977. At that time, Neptune was the farthest known body in the Solar System.
Voyager 2 was the first to be launched. Its trajectory was designed to allow flybys of Jupiter, Saturn, Uranus, and Neptune. Voyager 1 was launched after Voyager 2, but along a shorter and faster trajectory that was designed to provide an optimal flyby of Saturn's moon Titan, [21] which
Plot of Voyager 2′s heliocentric velocity against its distance from the Sun, illustrating the use of gravity assist to accelerate the spacecraft by Jupiter, Saturn and Uranus, and finally its encounter with Neptune's Triton. Very massive planets attract spacecraft towards them, through the gravitational force; this force accelerates the ...
New Berlin Observatory at Linden Street, where Neptune was discovered observationally. Neptune as imaged by the Voyager 2 probe in 1989. The planet Neptune was mathematically predicted before it was directly observed.
Voyager 2/ISS images of Uranus and Neptune released shortly after the Voyager 2 flybys in 1986 and 1989, respectively, compared with a reprocessing of the individual filter images in this study to ...
The last time Neptune's rings were seen in detail was during a flyby in 1989 by NASA's Voyager 2 spacecraft as it journeyed beyond the solar system and into interstellar space. That historic flyby ...
An enduring mystique surrounds the Voyager 1 and 2 probes. ... Neptune and Uranus. More than 47 years later, both spacecraft are still exploring the uncharted territory of interstellar space. And ...
